Facial nerve paralysis is a common problem that involves the paralysis of any structures innervated by the facial nerve. The pathway of the facial nerve is long and relatively convoluted, so there are a number of causes that may result in facial nerve paralysis. Facial nerve paralysis is characterised by facial weakness, usually only in one side of the face, with other symptoms possibly including loss of taste , hyperacusis and decreased salivation and tear secretion. Other signs may be linked to the cause of the paralysis, such as vesicles in the ear, which may occur if the facial palsy is due to shingles. Symptoms may develop over several hours. Bell's palsy is the most common cause of acute facial nerve paralysis.

A stroke occurs when the blood supply to the brain is suddenly blocked or when a blood vessel in the brain bursts. Deprived of oxygen, nerve cells in the affected area of the brain can't function and die within minutes. A person with loss of blood flow to the heart is said to be having a heart attack; similarly, a person with loss of blood flow to the brain or sudden bleeding in the brain can be said to be having a "brain attack. Although stroke is a disease of the brain, it can affect the entire body, including cognitive and memory deficits, speech problems, emotional difficulties, daily living problems, and pain. Paralysis is a common outcome of stroke, often on one side of the body hemiplegia. Paralysis may affect only the face, an arm or a leg, or it may affect one entire side of the body and face. A person who suffers a stroke in the left hemisphere of the brain will show right-sided paralysis, or paresis.
Facial nerve paralysis
Bell's Palsy is an impairment of the facial nerve that causes weakness or paralysis on one side of the face. It is the most common cause of facial droop, which is a term that indicates the look of a patient's face that is slack on one side from loss of muscle tone. The unaffected side of the face continues to have muscle movement and tone, which makes the affected side appear to "droop" in comparison. Facial droop is also a hallmark trait of the asymmetrical symptoms of a stroke.
Facial paralysis is a loss of facial movement due to nerve damage. Your facial muscles may appear to droop or become weak. It can happen on one or both sides of the face. Common causes of facial paralysis include:. Depending on the cause, the paralysis might last for a short or extended period of time.
